The wire which is to form the staple is preferably severed in advance of the staple forming operation, and the illustrated means for severing the wire comprises a cutter 48 carried by the outside former, said cutter cotiperating with a. wire guide 50 adjustably held in a groove in the part 42 by a set screw 52. The outside former is moved into coiiperative relation to the inside former to form the staple by means operated from a cam groove '54 in a cam disk 56 on the shaft 2, saidmeans comprising a lever arm 58having at its lower, end a segment rack 60 which engages rack teeth 62 formed upon the rear end of the outside former. The lever arm 58 is connected to a rock-shaft 64 fulcrumed in the machine" head. The other arm 65 of the rack operating lever is also connected to the rock-shaft 64 and is provided with a cam roll 66 which enters the cam groove 54. The oove 67 in the outside former which receives theinside former is enlarged at its lower side so that it forms a guiding roove 68 for the staple when itis being driven and also a guiding groove for the staple driver 69. Below the enlarged lower portion of the groove in the outside former there is a solid port-ion of the outside former which closes the groove and forms a support for the staple driver 69, this portion being extended at the front of the outside former to form a tongue 70 having a novel function hereinafter to be referred to. The staple driver 69 is T-shaped at its rear end and is connected to a rack slide 72 provided with a T-shaped opening to receive the T-shaped end of the driver, the construction of these parts being shown in detail in Fig. 7 of the drawings. Staple drivin movement is imparted to the driver through a lever 74 having at its lower end a segment rack 76 which engages the rack teeth of the rack slide 72. The lever 74 5 is connected to a rock-shaft 77 fulcrumed in The outside its bearings in the machine head. The rockshaft 98 projects through the upright 42 and carries at its outer end an arm 100 provided with a cam roll 102 which travels in a cam groove 104 in the cam disk 106. A spring 107 tends to keep the upper end of the slot 92 in engagement with the pin 94. The forward end of the guideway for the outside former, and for the staple driver, is formed in a nose 108 which is so shaped that it will enter between the lasting tacks of a lasted shoe and guide the staple in a substantially horizontal line through the upper and channel lip of the insole of said shoe, the guideway in said nose being in line with the clenching end of a staple clencher 110 carried by a dove-tailed slide 112 arranged to slide in a guideway 114 in a bracket 116 overhanging the nose 108. The slide 112 is connected by link 115, bellcrank lever 117, a yoke 119 engaging said bell-cranks 117, and a second link 121 -to a suitable treadle by which the staple clencher 110 may be moved into clamping relation to the nose 108. The nose 108 is preferably formed of two parts, a lower part 118 which contains an extension of the guideway 36 for the outside former and an upper part 120 which contains an extension of the T-shaped groove in the outside former, said outside former being arranged to move into approximately abutting relation to the rear end of the part 120 of the nose during the staple forming operation. The forward end of the part '120 of the nose 108 overhangs the part 118, and the tongue 70 upon the outside former is constructed and arranged to extend beyond the front end of the part 118 of the nose 108 when the outside former has completed its staple forming operation and thus close the lower sideof the staple and driver guiding opening in the part 120,

at the same time that it engages the upper and tucks it into the angle of union between the channel lip and the feather of the insole. The tongue 70 is tapered at its under side so that it tends to ride up over the edge of the insole as it presses the upper into position to receive the staple, this movement of the tongue serving also to force the shoe and last down and to bring the parts into such position that the staple is guided through the upper and channel lip in a line above the path of movement of the needle of the Welter in the welt stitching operation. It will be noted also that the, tongue 70 has a wiping as well as a pressing or tucking actionas it comes forward, the upward taper at the forward end of the tongue serving also to prevent injury to the upper as it is wiped over the corner of the last.

The wire 122 from'which the staples are to be formed may be carried by a. reel suitably positioned to permit the wire to pass readily to the wire feeding mechanism. The illustrated wire feeding mechanism comprises a feeding wheel 124 carried upon a feed wheel shaft 126 to which is connected a ratchet'wheel'128 arranged to be engaged by pawls 130 pressed toward the ratchet teeth of said ratchet wheel by a spring 132. The pawls 130 are carried by a disk 134 loosely mounted upon the shaft 126 and connected by a link 136 to the arm 100 upon the rock-shaft 98. The disk 134 may be provided with a slot 135 to receive the pivot 138 of the link 136, the pivot 138 being adjustable along the slot 135 toward and from the center of the disk 134 to give different lengths of movement to the pawls 130 and thereby vary the length of wire fed into staple forming position. A presser roll 140 keeps the wire in engagement with the feed wheel 124 and, to counteract the tendency of the wire to curve in one direction by reason of the pressure of the presser roll 140 thereon, a second roll 142 is provided which engages the wire at a different part of the periphery of the feed wheel 124, the two rolls 140 and 142 cooperating to curve the wire in a direction opposed to the direction in which it tends to curve as it leaves the roll 140. The roll 142 is carried by a bracket 144 provided with a pin 146 received in the forked end of an arm 148 clamped to the shaft which carries theroll 140. To vary the pressure exerted upon the wire by the roll 142 a set screw 150 is arranged in the bracket 144 to bear upon the arm 148 in such manner that the bracket 144 may be turned more or less about its pivot in the arm 148 as the screw 150 is turned. The rotation of the feed roll shaft 126 is retarded by a friction sleeve 152 clamped around a second sleeve 154 pinned to said shaft. 1

The operation of the machine as a whole may be briefly described as follows: The shoe to be operated upon is taken while still in its original lasted condition, with all the lasting tacks in place, and is presented to the machine in such a manner that the nose 108 enters between two of the lasting tacks 70. The nose being positioned to guide the.

staple into the desired location, the operator places his foot upon the treadle connected with the slide 112 and moves the clenching tool 110 into position behind the outer channel lip of the insole, if the shoe is provided with an insole of the ordinary type, and clamps the upper and channel lip tightly between the clenching tool 110 and the nose 108. The knee lever 30is then moved to actuate the clutch by which the loose pulley 10 is connected with the driving, shaft 2 and a staple is formed and driven in the manner hereinabove set forth. As the outside former 34 moves forward in the staple forming operation it carries with it the tucking tongue which, as it projects beyond the lower part 118 of the nose, engages the upper and tucks it into the angle of union between the feather of the insole and the channel lip, at the. same time drawing it over the edge of the last and tending to'shape it more closely to the last. As the outside former completes its movement the end of the tongue 70 will be substantially flush with the end of the nose 108, the tongue 70 forming the lower part of the staple guiding opening in said nose. The action of the tongue 70 as it comes forward also serves to depress the shoe or the insole and to position it in such a manner that the staple as it'is driven is guided through the upper and the channel 11p of the insole in a line above the path of movement of the needle of the Welter.

Although in the foregoing description of the operation of the machine it has been stated that the work is presented to the nose or throat and that theclenching toolis then moved into engagement with the work, it will be apparent that the operator, if he so desires, may present the work first to the clenching tool and then cause the clenching tool to move the work into engagement with the nose or throat. With some classes of work the mode of operation just described is preferable.

It will be understood that the operator, in selecting the place at which the staple is to be inserted, must consider both the location of the lasting tacks and the condition of the part of the nsole against which the staple is to be clenched. It is therefore important that the parts of the machine be so arran ed that the shoe may be adjusted freely a or it has been engaged by one of the members of the clamping means and before it has been, engaged by the other. important owing to the fact that the work upon which the machine is to operate is extremely irregular in its nature. This freedom of adjustment is secured in the machine illustrated by the normal separation of the nose'and clenching tool and by the location and arrangement of these parts.

so that no other part of the machine interferes with the free adjustment of the shoe.

It will be noted that..the outside former and the inside former havecooperating This is quite bevels whereby the wire which is to form the staple is maintained in the plane of the staple driver during the staple-forming operation. It will be noted further that the clenching tool 110 hasonly one half of an ordinary clenching cup whereby both ends of the staple are turned down. However as these last mentioned features do not constitute a part of my invention, they will not be claimed herein.

The improved method of making shoes in the practice of which the machine of this invention is especially useful has been made the sub'ect-matter of my co-pending application erial No. 585,060, filed Oct. 3, 1910 and the improved shoe made by that method has been made the subject-matter of my copending application Serial No. 597,054, filed December 13, 1910.
